Abstract
This structural foundation planning study takes the case of the Luwihaji-Medalem bridge construction project, Bojonegoro Regency with pile foundation planning. Foundations must be designed to meet the requirements for bearing capacity and controlled settlement, so that they do not exceed the specified permit limits. Calculations of bearing capacity and foundation settlement are based on data from the Penetration Test (SPT) standard. The analysis results from the Stadpro v8i program show that the total force and total weight of the bridge's upper structure is 250,761 tons. The results of the load analysis on the upper structure of the Luwihaji-Medalem Bridge, Bojonegoro Regency show that the maximum load that occurs in the reaction of the pillars and the Pu pile foundation is 2204.728 kN, with the largest bearing capacity occurring in the planning of the pile foundation (Spun Pile) with a depth of 22 meters and the pile diameter is 0.8 meters.
